There's some elastic and velcro at the opening of the Mic Muff. But to ensure it stays on the mic, I wrap a rubber band a bit behind the mic capsule, and the Mic Muff grips that and stays in place.

In the application I'm using it, the mic can sometimes have just a little bit too much midrange. Also, if I don't roll off the bass and there's a bit of wind, there's a very low-frequency rumble that has to be rolled off in post.

Lightwave still sells a few products. Not sure if it's what's left of their inventory but it seems the company went through some sort of transition phase. Their products seem to work pretty good.

I was going to modify my shotgun windscreen to fit the AT-4051 but there was no simple way of shortening the wind fur to fit a shorter windscreen. So I went ahead and ordered a new one.

I would think that, in theory, the Lightwaves furries
should be more effective than the Rycote
ones because the Rycotes (to my understanding)
do not have the dead airspace. I think the
Rycotes have the fur over the foam and then
the foam is in direct contact with the mic.
Someone correct me if I'm wrong about
the construction of the Rycotes.

I wrote earlier that at825b sounds like the stock pd 170 mic which it did with near by voice miking.

But at a wedding reception, they are worlds apart.

I did a reception and compared the two mics and the at835b sounded much more full compared to the stock mic. It had more bass and was clear. I also compared it to the at825 stereo mic which sounded more muddy but also better than the stock mic.
